National Incident-Based Reporting System (NIBRS) Series

Investigator(s): United States Department of Justice.
Federal Bureau of Investigation

The National Incident-Based Reporting System (NIBRS)
series is a component part of the Uniform Crime Reporting Program (UCR),
a nationwide view of crime administered by the Federal Bureau of
Investigation (FBI), based on the submission of crime information by
participating law enforcement agencies. The NIBRS was implemented to
meet the new guidelines formulated for the UCR to provide new ways of
looking at crime for the 21st century. NIBRS is an expanded and enhanced
UCR Program, designed to capture incident-level data and data focused
on various aspects of a crime incident. The NIBRS was aimed at offering
law enforcement and the academic community more comprehensive data
than ever before available for management, training, planning, research,
and other uses. NIBRS collects data on each single incident and arrest
within 22 offense categories made up of 46 specific crimes called Group A
offenses. In addition, there are 11 Group B offense categories for which
only arrest data are reported. NIBRS data on different aspects of crime
incidents such as offenses, victims, offenders, arrestees, etc., can be
examined as different units of analysis. The data are archived at ICPSR
as 13 separate data files, which may be merged by using linkage
variables.
